Abstract

Polarimetric characteristics of light from ocean water in combination with standard remote sensing reflectance provide important information about water constituents; they are useful in retrieval of additional water parameters like attenuation-to-absorption ratio and attenuation coefficients and/or establishing additional constraints for retrieval algorithms. The Stokes vectors of light above and below the water surface, which fully represent polarimetric characteristics of water leaving radiance, strongly depend on the particle size distribution and related Mueller matrices of water particulates. In this work we investigate the effect of various hydrosol mixtures of chlorophyllous particles on the polarized light field. The Stokes vectors of scattered light and the degree of polarization (DOP) are generated as outputs of vector radiative transfer simulations for various water compositions. Mie theory as well as T-matrix approaches are used for the generation of scattering matrices. The impact of their variability on the Stokes vectors of polarized light is analyzed.
